Hello - My AirBnb property is mostly used for guest in for business, training, and hospitals vs. vacationing. I have a guest looking to book for 4 months. I am perfectly fine doing this but would like her to do a credit check and to sign a short term lease. The AirBnb guest massaging tool doesn't allow me to send links thru and doesn't allow guest to send their cell or email. How does a host run credit checks and send leases? *Property is in Baltimore MD.
